The water from the " 1890 well " is lifted by an " Ashley " 

 patent double-acting bucket and plunger pump, worked by a 

 steam-engine (condensing), while that from the " 1904 well " 

 is lifted by the same type of pump — but with a larger capacity — 

 driven by a gas-engine working with suction gas. 



The water is pumped to a reservoir in the Park (3 on the 

 map), which has a capacity of 204,000 gallons. From the 

 reservoir the water gravitates back through another main, 

 to which the houses are directly connected. 



The water is analysed regularly by Prof. E. Kinch, of the 

 Royal Agricultural College, and the following is an analysis of 

 a typical sample : — 



Analysis of a Sample of Water from the 

 Cirencester Waterworks 

 obtained from the larger pump at the Pumping Station on 

 December 17th, 1913. 

 " The water was clear and bright ; the residue left on evaporation was 

 white and scarcely changed on heating. 

 " On analysis it yielded : 



Total solid residue at 100° C. . . 21-28 grains per gallon 

 Loss on heating .. .. .. i-i2 ,, ,, 



Chloride, expressed as common 



salt 1-37 



Oxygen, from potassium perman- 

 ganate, consumed by organic 

 matter in three hours . . . . trace only 



Nitrogen as Ammonia . . . . trace only 



Nitrogen as Albuminoid Ammonia 0-02 per million 

 Nitrogen as Nitrates . . . . 2-69 per million 



Temporary Hardness i5-5°\On Clark's Scale i.i\ grains of 

 Permanent Hardness 2-3°) Carbonate of Lime per gallon 

 " This sample was of accustomed good quality and purity. 

 ' ' The samples examined throughout the year have all been clear and bright 

 and in good condition. 



" The total solids have varied between 2i'28 and 22-33 grains per gallon. 

 The Chloride from 1-31 to 1-43 grains per gallon. The Free Ammonia from 

 none to trace. The Albuminoid Ammonia from o-oi to 0-05 per million, 

 and the Nitrogen as Nitrates from 2-5 to 2-78 per million." 



With regard to the deposits penetrated by the 1904 bore- 

 hole, such details as could be noted at the time by one of us 

 (T.H.) are set out on page 183. Down to 181 feet from the 

 surface a chisel-borer was used, and, therefore, no cores were 

 drawn. At the best, only small fragments of rock were ob- 

 tained. From 181 feet down to 267 feet, however, a calyx- 

 borer was employed, and therefore cores were drawn. Repre- 

 sentative specimens of these were saved, and have been 

 examined by one of us (L.R.V
